About the Role
We are seeking a seasoned Senior Information System Security Manager (ISSM) to support cybersecurity for an IL5/IL6 hybrid enterprise environment spanning cloud (AWS GovCloud, Azure Government) and on-premise systems within the Department of War (DoW). This role operates in a hybrid onsite/remote capacity, requiring approximately three days in our Fairfax, VA office.
As the high-level authority for the Cybersecurity Program, you will ensure compliance, manage risk, and maintain the security posture of information systems. You will navigate the complex Risk Management Framework (RMF) and operational deployment landscape across both Government and Commercial Off-The-Shelf (GOTS/COTS) environments. Your expertise will be leveraged to architect hybrid approaches that optimize system capabilities while maintaining robust cybersecurity defenses, rigorous Continuous Monitoring, and overall operational effectiveness.
This position represents the intersection between cybersecurity engineering, RMF compliance, strategic risk management, and innovative solutioning for network, hardware, software, and cybersecurity challenges. You will oversee Information System Security Officers (ISSOs), manage authorizations, and bridge the gap between technical teams and senior leadership, translating complex technical security challenges into business risk language for the C-suite.
Hiring Process
Candidates selected for this role must be U.S. Citizens with an active DoW Top Secret security clearance (TS/SCI preferred and ultimately required). The interview process will assess your strategic vision, technical depth in the RMF lifecycle, and ability to lead diverse teams in a high-stakes federal environment.
